9.0.5 Handling mass memory storage capacity
General In some cases it is very important that there is enough free space in the mass storage memory,
before attempting to download new system software. How to check its capacity, and if
required increase it, is detailed below.
A manual check on the free space can be done in one of the following ways:
Checking storage
capacity from the
Teach Pendant
Unit
1. Press the button Miscellaneous to select
Service window .
2. Select
Storage Capacity from the System Info menu. The Mass Storage
Memory is called hd0a .
Checking storage
capacity through
connection to the
MC/CONSOLE
port
1. Connect a console to the MC/CONSOLE outlet on the controller and execute the
command
dosFsShow .
There should always be at least 25 Mb free disk space on the controller mass storage memory
before attempting to download a new system. For information on how to increase storage
capacity, see below!
Increasing
storage capacity
If the capacity of the mass storage memory is less than 25 Mb when a new controller system
is to be downloaded, storage memory must be released by removing old systems from the
mass storage memory. This can be done in one of the following ways:
1. Boot up on the system you would like to remove and then make a C-START (see
section "C-start").
2. Use the FileManager in the Teach Pendant Unit, see User’s Guide - File Manager,
for more information on how to use the FileManager.
3. Use a third-party "ftp" client (like FTPVoyager supplied on the RobotWare CD).
Removing systems using the FileManager or FTP-client may be hazardous since the \bin and
BootRom.sys directories the must be kept intact.
Proceed with utmost care to avoid accidentally removing such files or directories!
